About this gig
Turn your idea into a working AI agent or knowledge assistant with LangChain. Please message me before ordering so we can agree on requirements and acceptance criteria.
BASIC: One single-task local agent prototype with one API tool.
STANDARD: One RAG agent using one document collection (up to 20 text-based PDFs, 200 pages total), one API tool, and a vector database.
PREMIUM: Standard scope plus a simple single-page web interface, up to two API tools, and deployment to one compatible environment.
All packages include source code, a setup guide, and testing against agreed examples. Basic includes one revision round; Standard and Premium include two. Revisions cover the agreed scope.
You provide authorized data, API access, and hosting. API, GPU, hosting, and third-party fees are separate. Model fine-tuning, OCR, native mobile apps, payments, and complex multi-agent systems require a custom quote. AI outputs can be incorrect; no accuracy or business-result guarantees.
I have LangChain and LoRA fine-tuning experience, published research, a Wuhan University bachelor's degree, and am pursuing a Computer Technology master's at Sun Yat-sen University (expected 2027).

I build websites, mobile apps, AI agents, RAG chatbots, API integrations, and workflow automation. My experience includes LangChain, LLM fine-tuning such as LoRA, and published research. I offer data preparation, training scripts, model evaluation, deployment, and bug fixes with an agreed scope. Wuhan University bachelor's, 2024; pursuing a master's in Computer Technology at Sun Yat-sen University, expected 2027. Native Chinese; IELTS 7.0 (Reading 8.0). Message me to discuss requirements, data, compute costs, and milestones.
FAQ
Can you fine-tune an LLM or build a website or app?
Yes. LoRA fine-tuning, training data preparation, evaluation, custom websites, mobile apps, and larger integrations can be scoped separately. Send your model, dataset size, compute availability, and goals for a custom quote. These are not included in the listed agent packages.
